Hi all,
Here is a peculiar situation that I am trying to resolve: I am
trying to deploy a simple web service that would connect in a "chain"
fashion to the back-end JDBC-Oracle connection class and retreive data from
the Oracle database. The "client" sees a simple JWS file as the endpoint
URL, and calls one of the JWS's methods. The method then calls a some other
classes, each which does its work and eventually the JDBC-Oracle class is
executed and result from the Oracle DB is pulled. However, I have this
mysterious error -- when I send from one of the "client" to a request to the
JWS web service file, I see the following error message as intercepted by
TCPMonitor:

This Caused by: java.lang.NoClassDefFoundError:
oracle/jdbc/driver/OracleDriver seems to be the cause of the error. However,
I can't figure out why tha happens: when I rename the JWS file as a Java
file and execute a "request" on the server side (i.e. pass all my parameters
on the "server" side to the Java file), it works perfectly. And yes, I have
included the JDBC-Oracle drivers in the classpath. I am using:
JBoss 3.2.1 with Jetty
Axis 1.1RC2
Oracle 8i (8.1.7.0.0)
Any insights into this?
Thanks!!
Lee
